About
LongWave Photonics is a California-based company founded in 2010 by Alan Lee and Qing Hu. It specializes in terahertz quantum cascade laser (QCL) systems for imaging, spectroscopy, and heterodyne receivers, and is based in Mountain View, California. The company offers compact, turnkey terahertz QCL systems with milliwatt average power levels across frequencies from 1.9 to 5 THz. The systems operate cryogen-free, need no optical alignment, and provide convenient terahertz sources for research and industrial use. LongWave Photonics has received funding from institutional investor Innobridge Capital and from the National Science Foundation through SBIR grants supporting NASA-related quantum photonics projects. Its terahertz quantum cascade lasers serve quantum sensing, spectroscopy, and imaging applications, addressing the terahertz gap in the electromagnetic spectrum. Uses include security screening, materials characterization, astronomical detection, and fundamental physics research.
